Please answer the second and last part.

B )   ( 14 X 2 + 43 X - 21 ) ÷ ( 7 X - 3 ) D )   ( ( 35 X 2 + 32 X - 99 ) ÷ ( 7 X - 9 )
 

b.     14x2 + 43x - 217x - 3=14x2 + 49x - 6x - 217x - 3=7x2x + 7 - 32x + 77x - 3=7x - 32x + 77x - 3=2x + 7d.      35x2 + 32x - 997x - 9=35x2 + 77x - 45x - 997x - 9=7x5x + 11 - 95x + 117x - 9=7x - 95x + 117x - 9=5x + 11
